That’s the plot of Steven Soderbergh’s latest and reportedly last film.

It begins with a clear vision—a noir Hithcockesque “whodunit.”

This movie has all the elements of a solid, clever picture. The heavyweight cast includes Jude Law, Rooney Mara (“The Girl with the Dragon Tattoo”), Channing Tatum, (yes, the stripper from “Magic Mike,” also a Soderburgh movie) and Catherine Zeta-Jones.

Yet, what audiences think will be an intelligent critique of the pharmaceutical industry suddenly goes off into a different orbit about 30 minutes into the film.

We are left with an unfocused, predictable, eye-rolling thriller bordering on preposterous.

Note: Reviewing a murder mystery is a delicate balance of not giving away too much, but just enough. I’ll try to restrain myself.

It begins with familiar foreshadowing. Someone has done something bad. Very bad. A murder. Blood. A weapon.

All that’s missing is the candlestick, the lead pipe and Colonel Mustard and Mrs. Peacock.

The who, what, where, how and why are largely unknown, but as the movie unfolded I became optimistic, and intrigued by the possibility that this would become a classic “whodunit.”

Enter Emily (Mara), a wife anxiously awaiting her husband’s (Tatum) return from a four-year prison sentence. He’s locked up for insider trading. She is depressed.
